A heated debate between “The View” hosts Joy Behar and Whoopi Goldberg and Bill O’Reilly on yesterday’s episode of the talk show culminated with Behar and Goldberg walking off set, the Huffington Post reports.

The topic of discussion? The proposed Islamic cultural center near Ground Zero, that has been characterized by some politicians and areas of the media as “The Ground Zero Mosque.”

According to the Huffington Post, the exchange became heated after O’Reilly declared a “gulf” between President Obama and the American people, because of the president’s qualified support of the cultural center.

The debate, full of exclamations to “listen to me” and “pinhead,” devolved into heated interruptions by both the hosts and O’Reilly, until O’Reilly said, “Muslims killed us on 9/11.”

Behar and Goldberg, after responding that extremists were responsible for the terrorist attacks and expressing their outrage at the statement, walked off the show’s set.

According to O’Reilly, his intention was not to insult Muslims, but that he was “tired of the political correctness surrounding the 9/11 attack. The truth is that if moderate Muslims around the world stood with Americans against radical Islam, the terrorists couldn’t exist…I’m not in the business of sugarcoating harsh realities.”
